GENERAL DESCRIPTION

The MX29LV320MT/B is a 32-mega bit Flash memory

organized as 4M bytes of 8 bits or 2M bytes of 16 bits.

MXIC's Flash memories offer the most cost-effective and

reliable read/write non-volatile random access memory.

The MX29LV320MT/B is packaged in 44-pin SOP, 48-

pin TSOP and 48-ball CSP. It is designed to be repro-

grammed and erased in system or in standard EPROM

programmers.

P/N:PM1129

- 2.7 to 3.6 volt for read, erase, and program opera-

tions

- 8KB (4KW) x 8 and 64KB(32KW) x 63

- Provides sector group protect function to prevent pro-

gram or erase operation in the protected sector group

- Provides chip unprotect function to allow code changes

- Provides temporary sector group unprotect function

for code changes in previously protected sector groups

- Provides a 128-word OTP area for permanent, se-

cure identification

- Can be programmed and locked at factory or by cus-

tomer

- Pin-out and software compatible to single power sup-

ply Flash

- Fast access time: 70R/90ns

- Page read time: 25ns

- Sector erase time: 0.5s (typ.)

- Effective write buffer word programming time: 22us

- 4 word/8 byte page read buffer

- 16 word/ 32 byte write buffer: reduces programming

time for multiple-word/byte updates

- Active read current: 18mA(typ.)

- Active write current: 50mA(typ.)

- Standby current: 20uA(typ.)

32M-BIT [4M x 8/2M x 16] SINGLE VOLTAGE 3V

MX29LV320MT/B

• Minimum 100,000 erase/program cycle

• 20-year data retention

SOFTWARE FEATURES

• Support Common Flash Interface (CFI)

• Program Suspend/Resume

• Erase Suspend/Erase Resume

• Status Reply

HARDWARE FEATURES

• Ready/Busy (RY/BY#) Output

• Hardware Reset (RESET#) Input

• WP#/ACC input

PACKAGE

• 44-pin SOP

• 48-pin TSOP

• 48-ball CSP

The standard MX29LV320MT/B offers access time as

fast as 70ns, allowing operation of high-speed micropro-

cessors without wait states. To eliminate bus conten-

tion, the MX29LV320MT/B has separate chip enable

(CE#) and output enable (OE#) controls.

MXIC's Flash memories augment EPROM functionality

with in-circuit electrical erasure and programming. The

- Flash device parameters stored on the device and

provide the host system to access

- Suspend program operation to read other sectors

- Suspends sector erase operation to read data from

or program data to another sector which is not being

erased

- Data# polling & Toggle bits provide detection of pro-

gram and erase operation completion

- Provides a hardware method of detecting program

and erase operation completion

- Provides a hardware method to reset the internal

state machine to read mode

- Write protect (WP#) function allows protection of two

outermost boot sectors, regardless of sector protect

status

- ACC (high voltage) accelerates programming time

for higher throughput during system
